Abstract
Abstract There is disclosed a licensee notification system for implementing a software sales system wherein license information for converting to executable form software that is presented to a user in non-executable form is communicated to the user from a management center on condition of payment of a charge, and the software is converted into executable form at the user terminal using this license information. The subject of the licensee notification system is software that decides whether or not the correspondence relationship between user identification information and signature information stored in the license file is legitimate, and, if it is legitimate, displays the user identification information to the user before starting proper operation; or, if it is not legitimate, does not start proper operation. The licensee notification system is constituted by connecting the management center and user terminals by communication circuits. If license information is requested from the user terminal, the management center transmits license information combining in integral form the user identification information identifying the user and conversion information for converting the software to executable form. The user terminal enables the software using the conversion information contained in this license information and writes user identification information and signature information whose content is determined in accordance with the content of the user identification information to a license file that is referred to when this software is operating.

Claim 2
Dependent Claim
200 words
A licensee notification system for use in a software sales system in which software in non-executable form is presented to a user, and license information for converting the software in non-executable form to executable form is informed to the user on condition of payment of a charge, said licensee notification system comprising: a management center including license information generating means for generating license information combining in integrated form the conversion information for converting software to executable form and user identification information specifying the user; and a user terminal including storage means, conversion means that converts the software in non-executable form into executable form using the license information generated by said license information generating means and installing the software in executable form in said storage means, and software rewriting means for rewriting the information in a prescribed location of the software installed by said conversion means with the user identification information contained in the license information generated by said license information generating means; and wherein the software includes instructions that commands the user terminal to read user identification information in the prescribed location in the software and to notify the user identification information to the user on commencement of its operation.
Claim 3
Dependent Claim
207 words
A licensee notification system for use in a software sales system in which software in non-executable form is presented to a user, and license information for converting the software in non-executable form to executable form is informed to the user on condition of payment of a charge, said licensee notification system comprising: a management center including license information generating means for generating license information combining in integrated form conversion information for converting software to executable form and user identification information specifying the user; and a user terminal including storage means; license file creating means for creating a license file containing the user identification information contained in the license information generated by said license information generating means, and for storing the license file in said storing means, and software execution means for converting, when execution of the software is designated, the software into executable form using the license information in the license file and expanding the software in executable form into memory and executing operation in accordance with the software in the memory; and wherein the software includes instructions that commands the user terminal to read user identification information in the license file and to notify the user identification information to a user on commencement of its operation.
Claim 4
Dependent Claim
193 words
A licensee notification system for use in a software sales system in which software that refers to license information is presented to a user, and the license information in respect of software is informed to the user on condition of payment of a charger said licensee notification system comprising: a management center including license information generating means for generating license information combining in integrated form user identification information specifying the user and signature information whose content is determined in accordance with the user identification information; and a user terminal including storage means, and license file creating means for creating the license file containing the license information generated by the license information generating means and storing the license file in the storage means, and wherein the software includes instructions that command the user terminal to judge the legitimacy of the user identification information in the license file using the signature information in the license file on commencement of its operation and, if the user identification information is legitimate, to commence proper operation after notifying the user identification information to the user, but, if the user identification information is not legitimate, to stop the operation.
